SpringBoot-(5)-properties的使用

项目中经常需要进行一些配置，一般会使用springboot默认的application.properties文件，也可以自己创建配置文件

一，application.properties配置

logging.path=/Users/zhang_guang_yang/IDEA15/Logs/

logging.file=SpringBoot.log

# strings

com.gy.dateFormatter=dd-MM-yyyy

# strings

com.pleasure.local=/files

# array

com.pleasure.urls[0]=http://www.baidu.com/

com.pleasure.urls[1]=http://www.google.com/

com.pleasure.urls[2]=http://www.blog.csdn.com/

# map

com.pleasure.admin[username]=pleasure

com.pleasure.admin[password]=123456

　　读取

　　1，通过一个配置类来读取：

package com.example.demo.config;

import org.springframework.boot.autoconfigure.session.StoreType;

import org.springframework.boot.context.properties.ConfigurationProperties;

import org.springframework.stereotype.Component;

import java.util.ArrayList;

import java.util.HashMap;

import java.util.List;

import java.util.Map;

/**

 */

@Component

@ConfigurationProperties(prefix = "com.pleasure")

public class AppProperties {

    private String local;

    private Map<String, String> admin = new HashMap<String ,String>();

    private List<String> urls = new ArrayList<String >();

    public String getLocal() {

        return local;

    }

    public void setLocal(String local) {

        this.local = local;

    }

    public Map<String, String> getAdmin() {

        return admin;

    }

    public void setAdmin(Map<String, String> admin) {

        this.admin = admin;

    }

    public List<String> getUrls() {

        return urls;

    }

    public void setUrls(List<String> urls) {

        this.urls = urls;

    }

}

　　获取属性

@RestController

@EnableAutoConfiguration

public class PropertiesController {

    @Autowired

    private AppProperties appProperties;

    @RequestMapping("/properties")

    public String properties(){

        System.out.println("local: " + appProperties.getLocal());

        System.out.println("admin: " + appProperties.getAdmin().get("username")；

        return success;

     }

}

　　2, @Value读取

　　@Value("${com.gy.dateFormatter}")

    private String dateFormat;

　　3，通过Environment对象读取

 　　@Autowired

    private Environment evn;

　　整个实现

package com.example.demo.controllers;

import com.example.demo.config.AppProperties;

import com.example.demo.domain.Info;

import com.sun.tools.javac.comp.Env;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.beans.factory.annotation.Value;

import org.springframework.boot.autoconfigure.EnableAutoConfiguration;

import org.springframework.core.env.Environment;

import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.bind.annotation.RestController;

/**

 * Created by zhang_guang_yang on 2018/11/20.

 */

@RestController

@EnableAutoConfiguration

public class PropertiesController {

    @Autowired

    private AppProperties appProperties;

    @Value("${com.gy.dateFormatter}")

    private String dateFormat;

    @Autowired

    private Environment evn;

    @Autowired

    private Info info;

    @RequestMapping("/properties")

    public String properties(){

        System.out.println("local: " + appProperties.getLocal());

        System.out.println("admin: " + appProperties.getAdmin().get("username") + " " + appProperties.getAdmin().get("password"));

        System.out.println("url: " + appProperties.getUrls().get(0));

        System.out.println("date formatter: " + dateFormat);

        System.out.println(evn.getProperty("com.gy.dateFormatter"));

        System.out.println("info: " + info.getName());

        return "success";

    }

}

二，自定义properties文件和类

　　1，info.properties

zgy.info.version=1.0

zgy.info.name="good mall"

zgy.info.bundleId="zgy.good.mall"

　　2, 定义类

package com.example.demo.domain;

import org.springframework.boot.context.properties.ConfigurationProperties;

import org.springframework.context.annotation.ComponentScan;

import org.springframework.context.annotation.PropertySource;

/**

 * Created by zhang_guang_yang on 2018/11/20.

 */

@ConfigurationProperties(prefix = "zgy.info")

@PropertySource("classpath:config/info.properties")

public class Info {

    private String version;

    private String name;

    private String bundleId;

    public String getVersion() {

        return version;

    }

    public void setVersion(String version) {

        this.version = version;

    }

    public String getName() {

        return name;

    }

    public void setName(String name) {

        this.name = name;

    }

    public String getBundleId() {

        return bundleId;

    }

    public void setBundleId(String bundleId) {

        this.bundleId = bundleId;

    }

}

　　3，注册扫描

@ComponentScan(basePackages = {"com.example.demo.domain"})

public class DemoApplication {

	public static void main(String[] args) {

		SpringApplication.run(DemoApplication.class, args);

	}

}

　　4，获取属性

　　@Autowired

    private Info info;
